** Description changed:
The dist-upgrader tarball includes configuration files for the release
upgrade process and part of the configuration file is a section with the
heading KernelRemoval which includes Version, BaseNames, and Types which
are used to build a list of kernels to remove. This section has not been
updated in quite some time and we should up date so systems have less
old kernels installed.
[Test Case]
1) upgrade a system from a release of Ubuntu to a new release of Ubuntu (this
should be done for the following paths B->C, C->D, B->D)
2) observe the following in /var/log/dist-upgrade/main.log
"2019-05-07 11:38:23,264 DEBUG identifyObsoleteKernels()
2019-05-07 11:38:27,621 DEBUG identifyObsoleteKernels found 'set()'"
The release upgrader from -proposed (do-release-upgrader -p) should
- identify some obsolete kernels even if it doesn't end up removing them.
+ identify some obsolete kernels ("skipping running kernel linux-
+ headers-5.0.0-13-generic") even if it doesn't end up removing them.
[Regression Potential]
I made the BaseNames section split out across multiple lines which should be
fine but that could cause the config file to fail to be parsed which would
probably cause a crash or the same failure to remove obsolete kernels.
